This listing is for a Complete Disc Brake Assembly kit that includes everything needed to mount disc brakes to a boat trailer that is running a single axle hydraulic disc brake system. From Front to Back, we have included all the needed hardware and parts for replacing an existing disc brake system, or to start fresh with disc brakes on your trailer for the first time. This system will outfit Leaf Spring and Torsion Axles.
This is a Hydraulic Disc Brake System that uses surge action to apply the brake pressure. In short, when your vehicle brakes are applied, the Surge Actuator compresses because of the forward "surge" created, which applies pressure to the hydraulic fluid, forcing it through the brake lines to the calipers, which compress on the brake rotors, and slow down your trailer. This process is extremely effective, and the most efficient way to have brakes on your boat trailer.
What makes this kit we have put together so unique, are the components included. We have included a Demco Brand Surge Actuator, Stainless Steel Mounting Bolts, Kodiak DOT Rated Flexible Brake Hoses, and Kodiak Brand Disc Brakes.
This Disc Brake kit is for 3500 lb trailer axles with a 4 Hole standard brake flange mounted to the axle. If your axle does not have this brake flange, you will not be able to mount brakes to your trailers axle.
